The Automated External Defibrillator referred to it by (AED) is a medical machine made to help in the case of sudden cardiac arrest.

It’s very similar to the ones that exist in the hospitals but this machine is specially designed to the use of non expert persons (but at least who have little information about using it and how to do the CPR).

The sudden cardiac arrest is the most dangerous killer and it differs from the Heart attack where the SCA is when something interferes with the electrical conduction process in the heart (here comes the role of the AED) while the heart attack occurs when blood flow to the heart muscle.

In the case of the SCA it’s so important not to let the heart stop so we have to play as the heart and that by doing the CPR while we should start with the AED as soon as possible to give the necessary electrical shocks to the body.

This machine is essential and in some countries it’s obligatory to exist in the public places same as it’s a very easy to use machine.
